Comparative Study Observational Study
Bilateral bispectral index monitoring during and after electroconvulsive therapy compared with magnetic seizure therapy for treatment-resistant depression.
Electroconvulsive therapy (ECT) is a highly effective and established treatment for depression. Magnetic seizure therapy (MST) has recently been developed and seems equally effective while associated with fewer side-effects. Both require general anaesthesia, which could be quantified using the bispectral index (BIS). We compared ECT and MST with respect to recovery times, left-sided BIS, and left-right differences in BIS. ⋯ At a comparable anaesthetic depth, MST is superior to ECT in terms of post-ictal recovery, which is correctly reflected by higher post-ictal BIS values. Unilateral BIS monitoring is sufficient to monitor anaesthetic depth in ECT and MST patients. TRIAL REGISTRY NUMBER: NCT 01318018.

Observational Study
Respiratory stroke volume variation assessed by oesophageal Doppler monitoring predicts fluid responsiveness during laparoscopy.
This study was designed to assess the ability of the stroke volume respiratory variation (ΔrespSV) determined by oesophageal Doppler monitoring (ODM) to predict the response to volume expansion (VE) during pneumoperitoneum. The predictive value of ΔrespSV was evaluated according to the concept of the 'grey zone'. ⋯ ΔrespSV and ΔrespPV predicted fluid responsiveness during laparoscopy under strict physiological conditions. FTc was not predictive of fluid responsiveness during laparoscopy.
